Description

Technical Field

[0001] This invention relates to the field of automotive housing casting technology, specifically to an automotive transmission housing casting apparatus. Background Technology

[0002] The gearbox housing is the structure used to install the transmission mechanism and its accessories. It primarily uses different gear combinations and a hydraulic system to generate speed and torque changes, thereby altering the rotational speed. Currently, gearbox housings are mainly obtained through casting. This involves using a closed, multi-faceted structure of a specific shape as a mold for the pre-formed part. Molten casting material (usually aluminum alloy) is poured into the mold, and after the molten material cools, a pre-formed housing blank or part is obtained.

[0003] Traditional gearbox housing casting mold cooling systems employ uniformly distributed cooling channels with coolant circulating at a constant flow rate. While this design maintains some effectiveness in castings with uniform wall thickness, it encounters numerous problems when dealing with the complexities of modern gearbox housings. In actual production, gearbox housings exhibit significant wall thickness variations. Thick-walled areas are prone to localized overheating due to insufficient cooling, leading to shrinkage porosity; thin-walled areas often experience thermal cracking due to overcooling. These problems severely compromise casting quality and performance, resulting in low production yields and high costs. Existing temperature control technologies often utilize uniform cooling channels, which are ill-suited to complex wall thickness distributions. Some improvements optimize cooling by increasing the number of cooling pipes or adjusting flow rates, but these methods fail to address the fundamental issue of matching cooling intensity with wall thickness variations. Slow heat dissipation in thick-walled areas prolongs solidification time, increasing the risk of shrinkage porosity defects; excessive cooling in thin-walled areas exacerbates thermal stress, inducing thermal cracking and affecting the mechanical properties of the casting. Furthermore, traditional cooling systems lack real-time monitoring and feedback mechanisms, making it impossible to dynamically adjust cooling intensity to adapt to temperature changes in different areas of the housing. During the casting process, factors such as fluctuations in coolant temperature and unstable flow rate further exacerbate the non-uniformity of the temperature field, leading to internal structural defects and dimensional deviations in the casting.

[0004] Therefore, based on the above-mentioned search and combined with existing technology, an automotive gearbox housing casting device is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a casting device for an automotive transmission housing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0009] Furthermore, the detection component includes: two connecting blocks, which are respectively fixedly installed on the inner wall of the lower mold, and each of the two connecting blocks has a moving groove on its adjacent surface. Multiple circular electromagnets are fixedly installed on the inner wall of each of the two moving grooves, and a moving block is slidably installed in each of the two moving grooves.

[0010] Furthermore, the detection assembly also includes: a fixing plate, which is fixedly installed on the adjacent surfaces of the two movable blocks, and temperature sensors are fixedly installed on both sides of the top surface of the fixing plate, and an ultrasonic thickness gauge is fixedly installed on one side of each of the two temperature sensors.

[0011] Furthermore, the circulation assembly includes: a liquid storage tank, which is fixedly installed on the front side wall of the portal frame; a partition is fixedly installed on the left side wall of the liquid storage tank; a centrifugal pump is fixedly installed on the top surface of the partition; and a coolant cooler is fixedly installed on the front side wall of the portal frame and on one side of the liquid storage tank.

[0012] Furthermore, the circulation assembly also includes: a first connecting pipe, which is disposed between the storage tank and the first connecting pipe and is used to transport the coolant in the storage tank to the centrifugal pump; a second connecting pipe is disposed between the centrifugal pump and one side of the main cooling pipe, which is used to transport the coolant in the centrifugal pump to the main cooling pipe; a third connecting pipe is disposed between the coolant cooler and the other side of the main cooling pipe and is used to transport the coolant in the main cooling pipe to the coolant cooler; and a fourth connecting pipe is disposed between the coolant cooler and the storage tank, which is used to transport the coolant in the coolant cooler to the storage tank.

[0016] 1. In this invention, by setting a cooling adjustment component, the distance between the cooling pipe and the casting shell can be dynamically adjusted. Combined with real-time temperature and thickness detection, the casting quality of the gearbox shell is significantly optimized. For the problem of local overheating or overcooling caused by wall thickness differences, the device can adaptively adjust the cooling intensity, so that the thick-walled area can dissipate heat quickly and the thin-walled area can avoid overcooling, thereby effectively reducing shrinkage porosity and hot cracking defects, improving the overall structural uniformity of the casting. At the same time, the closed-loop control system dynamically responds to temperature changes through intelligent algorithms to ensure the stability and reliability of the casting process and greatly improve the product yield.

[0017] 2. This invention employs an integrated coolant circulation and intelligent feedback mechanism to achieve efficient energy utilization. The coolant is rapidly cooled and reused during circulation via a precise temperature control module, significantly reducing energy consumption. Automated detection and adjustment functions reduce the need for manual intervention, not only improving production efficiency but also extending mold lifespan. It is suitable for large-scale continuous production of various shell types, demonstrating significant economic benefits and industrial application value. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In one typical implementation of this application, please refer to Figures 1 to 8 As shown, an automotive gearbox housing casting device includes: a portal frame 1, a lower mold 3 fixedly mounted on the inner wall of the portal frame 1 via multiple connecting rods 2, an automotive gearbox housing being provided on the top surface of the lower mold 3, a base plate 4 being provided on the bottom surface of the lower mold 3, an upper mold 5 being provided above the lower mold 3, a cylinder 6 being fixedly mounted on the top surface of the portal frame 1, the output end of the cylinder 6 being connected to the top surface of the upper mold 5, and when the cylinder 6 is started, the upper mold 5 will extend and retract synchronously with the extension and retraction of the output end of the cylinder 6, a power distribution box 30 being fixedly mounted on the left side wall of the portal frame 1 for supplying power to the device, and a controller 31 being fixedly mounted on the right side wall of the portal frame 1, with a processor 32 fixedly mounted on one side of the controller 31;

[0029] The cooling regulating component is located inside the lower mold 3 and includes:

[0030] The main cooling pipe 7 is fixedly installed on the inner wall of the lower mold 3. The main cooling pipe 7 is U-shaped. Rectangular blocks 8 are fixedly installed on both sides of the main cooling pipe 7. Rectangular grooves 9 are opened on the side walls of the two rectangular blocks 8. The cooling adjustment assembly also includes adjustment components. Multiple sets of adjustment components are provided and are respectively set in the two rectangular grooves 9.

[0031] The detection component is installed in the lower mold 3 and is used to measure the temperature and thickness of the lower mold 3.

[0032] A circulation component is mounted on the gate-shaped bracket 1.

[0033] As a preferred embodiment of this example, please refer to [link / reference]. Figure 7 and Figure 8 As shown, the adjusting component includes: a limiting rod 10, two limiting rods 10 are provided, the limiting rods 10 are fixedly installed inside the rectangular groove 9, a sliding block 11 is slidably installed on the outer surface of the limiting rod 10, a second cooling pipe 12 is provided on the side wall of the sliding block 11, a flexible hose 13 is provided between the second cooling pipe 12 and the main cooling pipe 7, and an annular electromagnet 14 is fixedly installed on the top surface of the limiting rod 10, the annular electromagnet 14 and the sliding block 11 cooperate with each other.

[0034] Based on the above features, the distance between the second cooling pipe 12 and the vehicle transmission housing can be adjusted. Specifically, when the detection component detects the thickness and temperature of the vehicle transmission housing, if it detects that the local temperature of the vehicle transmission housing is too high and exceeds a predetermined value, it will transmit the data to the processor 32. The controller 31 will activate the corresponding annular electromagnet 14, causing the annular electromagnet 14 to attract the sliding block 11. When the sliding block 11 moves on the limit rod 10, it will achieve a cooling effect, and the second cooling pipe 12 will move synchronously. Conversely, when it detects that the local temperature of the vehicle transmission housing is too low, the controller 31 will de-energize the annular electromagnet 14 or reduce the current, causing the sliding block 11 to move down. When the sliding block 11 moves down, the second cooling pipe 12 will move down synchronously, and the second cooling pipe 12 will move away from the vehicle transmission housing, thereby increasing its temperature.

[0035] As a preferred embodiment of this example, please refer to [link / reference]. Figure 6 and Figure 6As shown, the detection assembly includes: two connecting blocks 15, which are fixedly installed on the inner wall of the lower mold 3. The adjacent surfaces of the two connecting blocks 15 are provided with moving grooves 16. Multiple circular electromagnets 17 are fixedly installed on the inner walls of the two moving grooves 16. Moving blocks 18 are slidably installed in the two moving grooves 16. The detection assembly also includes: a fixing plate 19, which is fixedly installed on the adjacent surfaces of the two moving blocks 18. Temperature sensors 20 are fixedly installed on both sides of the top surface of the fixing plate 19. An ultrasonic thickness gauge 21 is fixedly installed on one side of each of the two temperature sensors 20.

[0036] Based on the above features, the thickness and temperature of the automotive transmission housing can be detected. Specifically, during the casting process of the automotive transmission housing, the circular electromagnet 17 in the moving slot 16 will be energized in sequence to move the moving block 18. When the moving block 18 moves, the fixed plate 19, as well as the temperature sensor 20 and ultrasonic thickness gauge 21 on the fixed plate 19, will also move. When the temperature sensor 20 and ultrasonic thickness gauge 21 move to the bottom of the automotive transmission housing, the moving block 18 will stop, allowing it to detect the temperature and thickness of the automotive transmission housing. When the temperature is found to exceed the predetermined value, the temperature sensor 20 and ultrasonic thickness gauge 21 will transmit the data to the processor 32. The controller 31 will control the adjusting component to adjust the second cooling pipe 12 according to the thickness and temperature of the automotive transmission housing.

[0037] It is worth mentioning that the specific steps for adjusting the second cooling pipe according to the thickness and temperature of the car's transmission housing are as follows:

[0038] 1. Startup of the detection component

[0039] Temperature sensor 20: Real-time acquisition of the temperature of the contact area between the lower mold 3 and the shell, with a measurement range of 0℃~600℃ and an accuracy of ±1℃.

[0040] Ultrasonic thickness gauge 21: detects the local thickness of the shell with a resolution of 0.1 mm and a scanning frequency of 10 Hz.

[0041] Movement control: The circular electromagnets 17 are energized in sequence, driving the moving block 18 to slide along the moving groove 16 at a speed of 5cm / s, covering twelve preset detection points (50mm apart) under the housing.

[0042] 2. Data transmission

[0043] Temperature and thickness data are transmitted to processor 32 via the CAN bus of controller 31, with a processing delay of <50ms.

[0044] Processor 32 preset threshold:

[0045] Temperature thresholds: 250℃ for thick-walled regions and 180℃ for thin-walled regions;

[0046] Thickness threshold: ≥8mm for thick-walled areas and ≤5mm for thin-walled areas.

[0047] 3. Data Analysis and Decision Making

[0048] Temperature-thickness correlation analysis

[0049] Processor 32 divides the region based on thickness data:

[0050] If the thickness is ≥8mm, it is marked as a thick-walled area, and the target temperature is ≤250℃.

[0051] If the thickness is ≤5mm, it is marked as a thin-walled area, and the target temperature is ≤180℃.

[0052] Dynamic mapping: Construct a two-dimensional matrix of temperature field and thickness to identify hot spots (temperature exceeding the target value by >10℃) and cold spots (temperature below the target value by >15℃).

[0053] 4. Adjustment command generation

[0054] Overheating scenario: When the temperature of a certain area exceeds the target value + 10°C, a cooling enhancement command is triggered;

[0055] Overcooling scenario: When the temperature is less than the target value of -15℃, a cooling reduction command is triggered.

[0056] The command is sent to the corresponding regulating component via controller 31 (each group of regulating components corresponds to a detection point).

[0057] 5. Adjustment of the position of the second cooling pipe 12

[0058] Electromagnet drive

[0059] Cooling enhancement: The controller 31 applies a 24VDC current to the annular electromagnet 14, generating a 150N magnetic attraction force, which pulls the sliding block 11 up 10mm along the limit rod 10 (maximum stroke 20mm), so that the second cooling pipe 12 is 3mm closer to the surface of the housing (initial distance 13mm→10mm).

[0060] Cooling is reduced: the current is reduced to 12VDC, the magnetic attraction force is reduced to 75N, the sliding block 11 is moved down by 5mm due to gravity, and the second cooling pipe 12 is moved away from the housing by 15mm.

[0061] 6. Coolant flow rate adjustment

[0062] The change in the position of the second cooling pipe 12 affects the local heat exchange efficiency:

[0063] At a distance of 10mm, cooling efficiency is increased by 40% (flow rate 2L / min → 2.8L / min);

[0064] At a distance of 15mm, the cooling efficiency decreases by 30% (flow rate 2L / min → 1.4L / min).

[0065] Hose compensation: Hose 13 is made of silicone material, which can withstand -50℃~200℃ and has a 200% expansion rate, ensuring no leakage when the second cooling pipe is moved.

[0066] 7. Dynamic feedback and closed-loop control

[0067] Real-time monitoring

[0068] Temperature sensor 20 updates data every 2 seconds, and ultrasonic thickness gauge 21 scans the thickness every 5 seconds.

[0069] If the temperature fluctuation is greater than ±5℃ / min, the high-frequency monitoring mode is triggered (temperature sampling rate 1Hz, thickness sampling rate 2Hz).

[0070] 8. PID parameter adjustment

[0071] Controller 31 uses a fuzzy PID algorithm to dynamically adjust parameters based on the error:

[0072] Scale factor (Kp): 2.5 for thick-walled region, 1.8 for thin-walled region;

[0073] Integration time (Ti): 8s in thick-walled region, 12s in thin-walled region;

[0074] Differential time (Td): 3s in thick-walled region, 5s in thin-walled region.

[0075] The output control quantity is converted into electromagnet current (0-24V linear mapping).

[0076] 9. Coolant circulation and thermal balance

[0077] Circulation system operation

[0078] Centrifugal pump 24 drives the coolant (50% ethylene glycol solution) to circulate at a speed of 2800 rpm, with a flow rate of 20 L / min and a pressure of 0.8 MPa.

[0079] The coolant cooler (27) maintains an outlet temperature of 25±2℃ and a heat dissipation power of 5kW.

[0080] Heat load matching

[0081] The coolant temperature rise in the thick-walled zone is 15℃ (inlet 25℃ → outlet 40℃);

[0082] The temperature rise in the thin-walled zone is 8℃ (inlet 25℃ → outlet 33℃).

[0083] The coolant returns to the cooler through connecting pipe 3 28, and after cooling, it flows back to the storage tank 22 through connecting pipe 4 29, with a circulation cycle of 3 minutes.

[0084] 10. Anomaly Handling and Security Mechanisms

[0085] Over-temperature protection

[0086] If the temperature in a certain area exceeds 300℃ for 10 seconds, an emergency shutdown will be triggered.

[0087] Cylinder 6 lifts the upper mold 5, interrupting the casting process;

[0088] The centrifugal pump (24) runs at full speed (35L / min) to cool down quickly.

[0089] 11. Thickness out-of-tolerance alarm

[0090] If the thickness deviation is > ±0.5mm, the ultrasonic thickness gauge 21 sends an alarm signal to the controller 31, indicating mold wear or abnormal positioning.

[0091] As a preferred embodiment of this example, please refer to [link / reference]. Figures 1-3 As shown, the circulation assembly includes: a storage tank 22, which is fixedly installed on the front side wall of the portal frame 1; a partition 23 is fixedly installed on the left side wall of the storage tank 22; a centrifugal pump 24 is fixedly installed on the top surface of the partition 23; a coolant cooler 27 is fixedly installed on the front side wall of the portal frame 1, located on one side of the storage tank 22; the circulation assembly also includes: a connecting pipe 25, which is disposed between the storage tank 22 and the centrifugal pump 24, for transporting the coolant in the storage tank 22 to the centrifugal pump 24. A connecting pipe 26 is provided between the centrifugal pump 24 and one side of the main cooling pipe 7. The connecting pipe 26 is used to transport the coolant in the centrifugal pump 24 to the main cooling pipe 7. A connecting pipe 3 28 is provided between the coolant cooler 27 and the other side of the main cooling pipe 7. It is used to transport the coolant in the main cooling pipe 7 to the coolant cooler 27. A connecting pipe 4 29 is provided between the coolant cooler 27 and the storage tank 22. The connecting pipe 4 29 is used to transport the coolant in the coolant cooler 27 to the storage tank 22.

[0092] Based on the above features, the coolant can be recycled. Specifically, when the car gearbox housing is being cast, the operator turns on the centrifugal pump 24 through the controller 31. At this time, the centrifugal pump 24 will transfer the coolant in the reservoir 22 to the main cooling pipe 7 through the connecting pipe 1 25 and the connecting pipe 26. After that, the coolant in the main cooling pipe 7 will increase in temperature during the process of the car gearbox housing. At this time, it will flow into the coolant cooler 27 through the connecting pipe 3 28 for cooling. Then, it will flow back to the reservoir 22 through the connecting pipe 4 29, forming a cycle.

[0093] Working principle:

[0094] In operation, the operator first activates the power distribution box 30 to supply power to the device, and the controller 31 and processor 32 complete initialization. Cylinder 6 drives the upper mold 5 to press down, closing with the lower mold 3 to form a cavity, thus beginning the casting of the automotive gearbox housing. The circular electromagnets 17 in the detection assembly are sequentially energized, driving the moving block 18 to slide along the moving groove 16 at a speed of 5 cm / s, covering 12 preset detection points (50 mm spacing) below the housing. The temperature sensor 20 on the fixed plate 19 (measuring range 0℃~600℃, accuracy ±1℃) collects the temperature of the contact area in real time, and the ultrasonic thickness gauge 21 scans the housing thickness at a resolution of 0.1 mm. Data is transmitted to the processor 32 via the CAN bus, with a processing delay of <50 ms. Thick-walled areas (≥8 mm): target temperature ≤250℃; thin-walled areas (≤5 mm): target temperature ≤180℃. When the temperature of a certain area > target value +10℃, a cooling enhancement command is triggered; if the temperature < target value -15℃, a cooling reduction command is triggered. Commands are sent to the corresponding adjustment components. The controller 31 applies a 24VDC current to the annular electromagnet 14, generating a 150N magnetic force. This pulls the sliding block 11 upwards along the limit rod 10 by 10mm, bringing the second cooling pipe 12 closer to the housing by 10mm (initial distance 13mm), increasing cooling efficiency by 40% (flow rate 2L / min → 2.8L / min). When the current drops to 12VDC, the magnetic force weakens to 75N, the sliding block 11 moves downwards by 5mm, and the second cooling pipe 12 moves 15mm away from the housing, reducing the flow rate to 1.4L / min. The hose 13 is made of silicone (200% elongation) to ensure leak-free movement. The centrifugal pump 24 drives the coolant (50% ethylene glycol solution) at 2800rpm, with a flow rate of 20L / min and a pressure of 0.8MPa. The coolant enters the main cooling pipe 7 through connecting pipe 26, absorbing heat and increasing in temperature: 15℃ in the thick-walled area (inlet 25℃ → outlet 40℃); 8℃ in the thin-walled area (inlet 25℃ → outlet 33℃). The high-temperature coolant enters the coolant cooler 27 through connecting pipe 3 28, cooling to 25±2℃ before flowing back to the storage tank 22 through connecting pipe 4 29, completing a 3-minute circulation cycle. Temperature sensor 20 updates data every 2 seconds, and ultrasonic thickness gauge 21 scans the thickness every 5 seconds. If the temperature fluctuation is >±5℃ / min, it switches to high-frequency monitoring mode (temperature sampling rate 1Hz, thickness 2Hz). The proportionality coefficient for the thick-walled area is 2.5, the integral time is 8s, and the derivative time is 3s; the proportionality coefficient for the thin-walled area is 1.8, the integral time is 12s, and the derivative time is 5s. If the temperature in a certain area exceeds 300℃ for 10 seconds, cylinder 6 lifts the upper mold 5 to interrupt casting, and centrifugal pump 24 runs at full speed of 35L / min for emergency cooling. Thickness deviation alarm: When the thickness deviation is > ±0.5mm, the ultrasonic thickness gauge 21 sends an alarm signal to indicate that the mold is abnormal.

[0095] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
